This option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.

 5305:      * Returns the PDF string code to print a cell (rectangular area) with optional borders, background color and character string. The upper-left corner of the cell corresponds to the current position. The text can be aligned or centered. After the call, the current position moves to the right or to the next line. It is possible to put a link on the text.<br />
 5306:      * If automatic page breaking is enabled and the cell goes beyond the limit, a page break is done before outputting.
 5307:      * @param float $w Cell width. If 0, the cell extends up to the right margin.
 5308:      * @param float $h Cell height. Default value: 0.
 5309:      * @param string $txt String to print. Default value: empty string.
 5310:      * @param mixed $border Indicates if borders must be drawn around the cell. The value can be a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul> or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul> or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
 5311:      * @param int $ln Indicates where the current position should go after the call. Possible values are:<ul><li>0: to the right (or left for RTL languages)</li><li>1: to the beginning of the next line</li><li>2: below</li></ul>Putting 1 is equivalent to putting 0 and calling Ln() just after. Default value: 0.
 5312:      * @param string $align Allows to center or align the text. Possible values are:<ul><li>L or empty string: left align (default value)</li><li>C: center</li><li>R: right align</li><li>J: justify</li></ul>
 5313:      * @param boolean $fill Indicates if the cell background must be painted (true) or transparent (false).
 5314:      * @param mixed $link URL or identifier returned by AddLink().
 5315:      * @param int $stretch font stretch mode: <ul><li>0 = disabled</li><li>1 = horizontal scaling only if text is larger than cell width</li><li>2 = forced horizontal scaling to fit cell width</li><li>3 = character spacing only if text is larger than cell width</li><li>4 = forced character spacing to fit cell width</li></ul> General font stretching and scaling values will be preserved when possible.
 5316:      * @param boolean $ignore_min_height if true ignore automatic minimum height value.
 5317:      * @param string $calign cell vertical alignment relative to the specified Y value. Possible values are:<ul><li>T : cell top</li><li>C : center</li><li>B : cell bottom</li><li>A : font top</li><li>L : font baseline</li><li>D : font bottom</li></ul>

 5913:      * Text can be aligned, centered or justified. The cell block can be framed and the background painted.
 5914:      * @param float $w Width of cells. If 0, they extend up to the right margin of the page.

 5917:      * @param mixed $border Indicates if borders must be drawn around the cell.

 5918:      * @param string $align Allows to center or align the text. Possible values are:<ul><li>L or empty string: left align</li><li>C: center</li><li>R: right align</li><li>J: justification (default value when $ishtml=false)</li></ul>
 5919:      * @param boolean $fill Indicates if the cell background must be painted (true) or transparent (false).

 5925:      * @param boolean $ishtml set to true if $txt is HTML content (default = false).
 5926:      * @param boolean $autopadding if true, uses internal padding and automatically adjust it to account for line width.
 5927:      * @param float $maxh maximum height. It should be >= $h and less then remaining space to the bottom of the page, or 0 for disable this feature. This feature works only when $ishtml=false.
 5928:      * @param string $valign Vertical alignment of text (requires $maxh = $h > 0). Possible values are:<ul><li>T: TOP</li><li>M: middle</li><li>B: bottom</li></ul>. This feature works only when $ishtml=false.
